ABSTRACT:
An amplification apparatus is disclosed. The amplification apparatus includes a plurality of emitters formed on a first substrate, an anode formed adjacent to a second substrate, so that current can be conducted between the emitters of the first substrate and the anode of the second substrate. A lens is formed adjacent to the emitters for controlling a magnitude of the current, thereby providing amplification of a signal applied to the lens. An inter-substrate material connects the first substrate and the second substrate, forming a vacuum that includes the emitters, the anode and the lens. Either the first substrate or the second substrate includes solid state memory. An alternate embodiment includes a storage medium for receiving an electron beam from the electron emitter, the storage medium having a storage area, the storage area being in one of a plurality of states as determined by an electron beam generated by the electron emitter.
